This is the Stanford dragon model available for free download in various formats.  There are some scientific differences between this model and the original .PLY from Stanford.  The dragon’s absolute size has been increased to 1.174′ by .525′ by 0.828′ and the pivot is repositioned to the base rather than the center of the object.  There are 50,000 vertices and 100,000 triangles.

This is a great all-around tester like the dragon model. I’ve gotten great use out of it for sub-surface scattering tests due to it’s great blend of thick and thin geometry!

This is the Stanford bunny model available for free download in various formats.  There are some scientific differences between this model and the original .PLY from Stanford.  The bunny’s absolute size has been increased to 0.836′ by 0.648′ by 0.829′ and the pivot is repositioned to the base rather than the center of the object.  There are 34,835 vertices and 69,666 triangles.

This is a great tester for volumetric effects because it has a large body with relatively thin geometry along the ears.  And it’s just so gosh-darn cute!
